Why Cotton × Utu?
Together, both brands are helping keep plastics off your skin and out of the outdoors.
Cotton provides an essential first layer
Soft, breathable, and naturally microplastic-free, 100% cotton underwear and tanks help protect your most intimate areas.
Utu protects what sees the sun
Protects exposed skin with high-performance SPF Outdoor Skincare® formulated without plastic-based ingredients and packaged in recyclable aluminum.
Treat what you wear like what you apply.
Every day begins with what touches your skin. Start with natural cotton, then finish with Outdoor Skincare®.
100% Natural Cotton
Soft, breathable natural fibers designed for everyday comfort.
Free from Microplastics
Natural cotton fibers don't shed synthetic microplastics during laundering. Paired with Utu's Outdoor Skincare® - formulated without plastic-based ingredients and packaged in recyclable aluminum - it's a more thoughtful approach to what touches your skin.
Your Essential Layer
Natural cotton for the skin you cover. Outdoor Skincare® for the skin you expose.
